Role is not refresh until we restart pentaho

Hi
We are using Pentaho 8.0 Comunity Edition CDE which is configure with SSO (Key Cloak)

I am facing issue which is when i assigned new role to any user it did not reflect in PUC until i restart my server.

If i restart my pentaho server then new role appear for the user.

My question, Is there any API or any method which will refresh roles



Thanks
Naimish
